PATENT OFFICE.

Assrenoa, BY MEsNE Assicu- MENTS, TO THE LUCE SPRING HINGE COMPANY, OF PORT WASHING- TON, VISCONSIN.

SPRING-HINGE.

SPECIFICATION forming To all whom it may concern.-

Be it known that I, BENONT GoLvIN, a citizen of the United States, residing at Freeport, in the county of Stephenson and State of Illinois, have invented certain new and useful Improvements in Spring-Hinges for Doors, of which the following is a speciication.

The object of this invention is to produce double-action adjustable spring-hinges which combine the advantages of simplicity of construction, durability, and great strength.

This invention consists in so constructing springhinges that they will hold a door either open or closed, according as desired, and that admit of having their opening and closing force easily and quickly regulated.

In the accompanying drawings, which form a part of this specification, Figure 1 is a view of a front elevatio of my improved hinge in position to hold a door closed. Fig. 2 is aview of a rear elevation of the saine hinge in position to hold a door open. Figs. 3 and 4 are topend views of Figs. 1 and 2, respectively. Figs. 5, 6, 7, 8, 9, and 10 are isometrical views of various parts of the hinge. Figs. 11 and 12 are views in detail of parts of the same.

Like lettersof reference indicate corresponding parts throughout the several views.

A represents a view of a hinge-plate provided with the hooks A and ears A2 A5, the former ear supporting the cylindrical pintle A5, the latter ear having the semi-cylindrical slot A5.

B represents a view of a counterpart hingeplate, provided with the hooks B and ears B" B3, the former ear being pierced by the circular opening B", which should be of proper diameter to readily admit the pintle A4, and the latter ear having the semi-cylindrical slot B5, which should be of the same dimensions as the slot A5.

. C represents a hinge-leaf provided with the eyes'G, forreceiving the hooks A of the hingeplate A.

C C3 represent ears, the-former provided with the vertical slot c and boss e', the circular opening C" extending entirely through the parts c' O, the latter having the circularopcning C5.

part of Letters Ratent No. 361,989, dated April 26, 1887.

(Model.)

D represents a counterpart hinge-leaf provided with the eyes D', for receiving the hooks B' of the hinge-plate B, and deteut d, for locking a part to be hereinafter described.

D2 D3 represent ears, the former provided with the pintle D4, of proper diameter tof readily enter the lower end of the circular opening C* of the ear G2, the latter having the circular opening D5. a

E represents a pintle-key furnished with a thumb-piece, E', having the pintle portion E'l cylindrical in form and the key portion E5 squared, or of any other suitable shape.

' F represents a circular spring-cap having a portion of its periphery indented with notches F, and provided with the slot F2 and boss F3.

A rectangular opening, Ft, of sufficient size to admit the key E3 of the pintle-key E, extends through the spring-cap F. and boss Fi.

To put the parts of the hinge `together, insert the pintle D* into the lower end of the openingC* ofthe ear C, putting the ear D3 of the hinge-leaf D immediately below the ear C3 of the hinge-leaf O, bring the edges a: of hinge-leaves C D together, pass the hooks A of the hinge-plate A through the eyes C ot' the hinge-leaf C, insert the pintle A* into the opening B* of the ear B, and insert the hooks B of the hinge-plate B through the eyes D of the hinge-leaf D, placing the ear B5 of the hinge-plate B immediately above and upon the ear A5 of the hinge-plate A. Next open the hinge-plates A B, and they, together with the hinge-leaves C D, will assume thc positions shown in Figs. 1 and 3. Then place the part G of the spiral spring G into the slot F2 of the spring-cap F, place the part Gi o f said spring into the slot c in the ear Gioi the hingeleaf C,aud press the spring-cap F below the 'ear D5, letting the detent d of the spring-leaf D drop into a notch, F', of said spring-cap. When the parts have been arranged as indicated, the axes of the circular openings A5, B5, C5, and D5 through the ears A, B3, C5, and D, respectively, and the middle joint of the rectangular opening F* through the springcap F, willliein one and the same straight line. Insert the pintle-key through the last-named openings and the spiral spring G, letting the end of the key enter the opening C* in the boss c.

To tighten the spring G, press on the top of the pintle-key E until the spring-cap F is r- 5 leased from the detent d, turn the pintle-key to the left, and let another notch F of the spring-cap engage the detent d.

The hooks-A B of the hinge-plates A B form, with the eyes C D of the hinge-leaves ro C D, secondary hinges, which allow the hingeleaves C D and the spring G, inclosed between them, and the hinge-cap F and pintle-key E,

t0 swing inward or outward, according as the door is closed or opened, as shown in Figs. 3 15 and 4, respectively.

The result of the outward and inward motions of the parts C, D, E, F, and G is to carry the dead-point or" the hinge outward or inward Y far enough to reverse the action of the spring G. 2o Accordingly, every time a door to which this spring is attached is opened wide or partially closed the action of the spring G is reversed and holds the door either open or closed, according to the position in which it e 5 is left by the operator.

I claim-- s' In a doublc-action adjustable springhinge,

latter cleft by the slot B5, the hinge-leaf C,

having the eyes C and ears C2 C2, the former provided with the slot c and boss c', which, With the ear C2, is perforated by the circular opening C, the latter ear also being perforated by the circular opening C5, the hinge-leaf D, having the detent d and ears D2 D3, the former provided with the pintle D, the latter perforated by the circular opening D5, the I pintle-key E, the spring-cap F, provided with the notches F', the slot F2, and central rectangular opening, F, and the spiral spring G, substantially as described, and for the purpose specified. Y

In testimony whereof I affix my signature in l the presence of two witnesses.
